a) In terms of electrons, state the function of a reducing agent.b) Identify a reducing agent used in the extraction of ironwrite an equation for the redox reaction in which iron if formed from iron (iii) oxide using this reducing agent.c) Identify a reducing agent used to obtain titanium metal from titanium (iv) cholrideIn addition to a high temperature, state a condition that is used for this reaction and explain why this condition is necessary.d)i) State two essential conditions used for the electrolytic extraction of aluminium from aluminium oxide.ii) Write an equation to illustrate how aluminium is formed form aluminium ions in the process.
Yes they may be AluminumOr you can even use old Steel 55 galoil drumsJust seal all openings.
Many pontoons are aluminumYou will some old logs that are steel.
Most pontoons on commercially manufactured pontoon boats are indeed aluminumHowever, there are a few manufacturers that make them with steel, and a few more that make them using wood with fiberglass overThe later (steel and fiber-glassed pontoons) are generally found on your larger pontoon vessels I used to have a 48' houseboat that had pontoons made out of plywood and then fiber-glassed John
a reducing agent donates an electron mixing iron oxide (any form of iron oxide) and powdered elemental aluminum (or a number of other metal powders) powder yields alumina and elemental iron upon ignitionthis is a mixture called thermite magnesium can be used as a reducing agent for titanium (iv) chloride in the kroll processThis is something I'm less familiar with, but, wikipedia says formation of lower chlorides of titanium are a problemWith that in mind, my guess at a solution would be to have an excess of reducing agentTo electrolyze aluminum, the aluminum/aluminum oxide should be molten and the electrodes shouldn't react with either the reactants or products 2Al2O3 + e- - 4Al +3O2 (I'll let you figure out the )
